SPECIFICATION forming part of Letters Patent No. 742,856, dated November 3, 1903. Application filed September 1'7, 1903. Serial No.'173,54=5. (No model-) To all whom it may concern:

Be it known that 1, JAMES W. GLADSTONE, a subject of the King of Great Britain, and a resident of West Orange, in the State of New Jersey, have invented certain new and useful Improvements in Batteries, of which the following is a specification accompanied by drawings.

Thisinvention relates to batteries, but more particularly to primary batteries; and its objects are to improve upon the construction of such batteries, secure simplicity and compactness, and increase the internal conductivity.

Another object of the invention is to improve upon the construction of the sustainingframe and clamping devices carried thereby for one of the electrodes.

Further objects of the invention will hereinafter appear; and to these ends the invention consists of a battery for carrying out the above objects, embodying the features of construction, combinations of elements, and arrangement of parts having the general mode of operation, substantially as hereinafter fully described and claimed in this specification and shown in the accompanying drawings, in which Figure 1 is a side elevation, partly in section, of a battery embodying the invention. Fig. 2 is a side elevation of a portion of the Fig. 3 is an edge view of the supporting-frame or hanger with the detachable spring-clamp removed. Fig. 4 is a transverse sectional plan view on the line m a: of Fig. 1. Fig. 5 is a detail side view of the detachable spring-clamp looking at the rear. Fig. 6 is a detail side view of'the detachable spring-clamp looking at the front, and Fig. 7 is a top plan view of the detachable spring-clamp.

Referring to the drawings, A represents a suitable container or vessel for the battery, provided with the cover B, of any suitable material, as porcelain. As shown, a rubber ring 0 encircles the cover for cushioning the same within the container. The negative plate D may be of copper oxid properly molded, and it is supported from the cover B within the vessel by a supporting-frame or hanger (shown in this instance substantially U-shaped) and consisting of the side bars E and cross-bar F. The hanger may be of plain copper wire of a suitable gage bent into the desired shape and in this instance provided with screw-threaded ends G, afiording provision for supporting and clamping the hanger from the cover by means of the nuts H. Binding-screws are provided for attaching the connecting-wires.

The hanger is provided with spring-clamps, one being detachable. The clamp J is suitably secured to the side bars E by means of the rivets K, which in this instance project at the front of said bars and are provided with heads L, affording a means for detachably securing the other spring-clamp O to the frame. The negative plate is secured and held firmly between the two spring-clamps J and O. In this instance the detachable spring-clamp O is provided with apertures P, adapted to fit over the headed ends L of the rivets K. The apertures P are provided with reduced portions Q, adapted to cooperate with the shanks of the rivets K after the larger portions P of the apertures have been passed over the heads of the rivets. In this manner the clamp O is securely held in place by means of a catch or locking connection and as readily may be detached. Preferably the clamps Oand J are perforated to afford free circulation of the electrolyte, and they are also preferably bowed, as shown more particularly in Fig. 4, so that when the detachable clamp O is secured in position the clamps press tightly against the plate and make good contact therewith. The invention is not to be understood as limited to the particular form of catch or looking connection shown for the detachable springclamp, as other suitable means may be provided for carrying out the same ends, I having illustrated the preferred form of the invention.

The positive or zinc plates R are arranged in this instance at each side of the copperoxid plate D and are cast onto a U-shaped casting, suitably secured to the cover B by means of the bolt or rod S, having a screwthreaded upper nut with which the nut T cooperates. A binding-screw U is provided for the connecting-wires. In order to prevent local action between the plate It and the side bars E, insulating-sleeves V are arranged upon the upper portions of the side bars.

Any suitable electrolyte may be used, preferably a twenty-per-cent. solution of caustic soda or other caustic electrolyte.

Any desired number of the spring-clamps may be used, I having shown but two for convenience of illustration.

Obviously some features of this invention may be used without others, and the invention may be embodied in widely varying forms.

Therefore, without limiting the invention to the construction shown and described nor enumerating equivalents, I claim and desire to obtain by Letters Patent the following:

1. In a battery, the combination with an electrode and a supporting-frame or hanger therefor, of perforated cooperating springclamps for the electrode supported by the hanger, one of said clamps being detachable from the hanger, substantially as and for the purposes set forth.

2. In a battery, the combination with an electrode and a supporting-frame or hanger therefor, of perforated cooperating springolamps for the electrode supported by the hanger, one of said clamps having detachable locking connection with the hanger, substantially as and for the purposes set forth.

3. In a battery, the combination with an electrode and a supporting-frame or hanger therefor, of perforated cooperating springclamps for the electrode supported by'the hanger, one of said clamps having eye1etholes adapted to engage with studs on the hanger, whereby said clamp may be bodily detached from the hanger, substantially as and for the purposes set forth.

4. In a battery, the combination with an electrode, of a U-shaped supporting-frame or hanger, provided with a fixed, perforated springclamp and a detachable perforated spring-clamp, substantially as and for the purposes set forth.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

JAMES W. GLADSTONE.
